Analytical Expressions for the Distortion of Asynchronous Sigma-Delta Modulators
نویسندگان
چکیده
This work investigates the commonly used Asynchronous Sigma Delta Modulator which consists of a schmitttrigger and a continuous time loop filter. A detailed analysis is presented to accurately predict the distortion of such modulators. The extracted expressions are compared with simulation results and they illustrate an excellent match. The results are also compared with a previous work by Roza and they show a drastic improvement in accuracy.

متن کاملEffect of non-linear settling error on the harmonic distortion of fully-differential switched-current bandpass Sigma-Delta modulators
This paper presents a detailed study of the effect of the non-linear settling on the harmonic distortion of Bandeass ZA Modulators (BP-UMs) realized using Fully Differential (FD) &vlrched-current (SI) circuits. Based on the analysis of building blocks, closed-form expressions are derived for the third-order intermodulation distortion of BP-XAMs due to defective settling, on the one hand, and to...

متن کاملNonlinearities in Sc Delta-sigma A/d Converters
The effects of using nonlinear low-gain opamps in switchedcapacitor delta-sigma modulators are analyzed. Using unconventional topologies, the state variables are made essentially uncorrelated with the input signal, hence opamp nonlinearity will cause very little harmonic distortion. Nonlinearity errors, whch are uncorrelated with the input, are called non-harmonic distortion. Using a correlated...
